02.1022

Carrier OCM 650, 20 mm with screen holder

This module can mount optical screens. Through the attached carrier, the screen holder can be placed onto the optical rail. The carrier 20 mm and the holder are made out of special anodized aluminum.
 

02.1602

Screen with scale

Experimental results like colour spectra and interference patterns can be visualized on these screens. Horizontal or vertical scales allow calibrations and quantitative measurements; a screen with an aperture is used for observing back-reflected rays. The screens are made out of anodized aluminum plates with one side painted white and can be fixed onto screen holders (02.1022, 02.1608).

Mounting plate OCM 650 for click 25, including carrier 20 mm
Mounting plate OCM 650 for click 30, including carrier 20 mm

Mounting plates are used to hold optical mounts. A characteristic feature of the mounting plates is the “click” mechanism of the inserts based on spring loaded spheres. Snapping in the groove of the inserted click mount, the optical element is kept in an exact position. On the other hand, the system allows a quick and easy change of the mounted inserts.
The mounting plates are made out of special anodized aluminum. Mounted onto the carrier 20 mm, the mounting plates can be placed onto an optical rail.

4 axis adjustment holder KH650, theta, phi, X and Y, including carrier 20 mm

This adjustment holder mounts a Diode Laser or an LED lamp. Using the fine pitch adjustment screws, the optical axis can be aligned within the range of 3 mm. For fine alignment of the angle of the light beam, two additional pitch adjustment screws are attached onto the back of the holder. The holder and the carrier 20 mm are made out of special anodized aluminum and can be placed onto an optical rail.
 

Plano convex lens f=40 mm, mounted in click 30 mount
Biconvex lens f=-20, mounted in click 30 mount

different glass lenses are mounted onto a special anodized aluminum click mount 30 mm by two threaded mounting rings to be used in connection with a mounting plate (02.2132).
 

Half wedge plate, mounted in click 25 mount

The half-wedge plate acts only on one part of the light beam and lets the other remain. Behind the plate, both parts of the beam intersect and cause interference. The half-wedge plate is mounted onto a special anodized aluminum click mount 25 mm by two threaded mounting rings to be used in connection with a mounting plate (02.2126).
Dia:
22,4 mm
 

Half lens f=100 mm, mounted in click 25 mount

The half-lens acts only on one part of a light beam and lets the other remain. Behind the lens, both parts of the beam intersect and cause interference. The half-lens is mounted onto a special anodized aluminum click mount 25 mm by two threaded mounting rings to be used in connection with a mounting plate (02.2126).
Dia:
22,4 mm
 

Fresnel plate, mounted in click 25 mount

A plastic foil with concentric rings acts as a Fresnel plate. The plate is mounted onto a special anodized aluminum click mount 25 mm by two threaded mounting rings to be used in connection with a mounting plate (02.2126).

Fabry Perot insert

This semi-transparent high quality mirror in a holder exchanges the spherical lens in the Newton’s rings assembly. The two plates in the assembly cause interference; effects can be influenced by turning the two plates respectively to each other. The mirror is fixed onto a 25 mm special anodized aluminum ring mount.
Dia:
22,4 mm
 

Plano convex lens f=20, mounted in click 25 mount with attached light tube

This glass lens mounted onto a click mount 25 mm attached by a light tube is used to focus the light on the detector and reduce the scattered light coevally using the light tube. The whole tube is made out of special anodized aluminum.
Length: 55 mm

LED white in housing

As universal and easy-to-change light sources, LED lamps are used in optical experiments. The LEDs are mounted onto a 40 mm x 25 mm diameter housing tube made out of special anodized aluminum. For the alignment, the lamps can be fixed onto a four axis adjustment holder mounted onto a carrier. For their operation, the active LDD-05 power supply (07.0206) is required which controls the output power. For the lamps 1 W (white LED: 3W), high brightness LEDs are used.
 

DIMO diode laser module, 532 nm (green) HC

Due to its excellent coherence properties, this frequency doubled green YAG laser is used specifically for interference experiments. The linearly polarized laser in its 60 mm x 20 mm diameter housing tube is made out of special anodized aluminum. It can be fixed onto a four axis adjustment holder and can be aligned to the optical axis. Driven by the LDD-05 active power supply (07.0206), the output power is controlled in the range from
 

LDD-05 active power supply

The universal LDD-05 active power supply is used for all laser and LED light sources. It recognizes which source is connected and sets the parameters for it automatically. The unit is equipped with a main switch, a regulation knob for adjusting the laser or LED power and a safety lock. The provided USB bus interface allows control through a personal computer or laptop and qualifies this unit as multimedia source.
The housing is made out of shock-proof plastic with an aluminum front and rear panel.

Voltage: 230 VAC / 50 Hz
Case dimensions: 200 mm x 160 mm x 62 mm.
 

The beam expander, consisting of two lenses mounted onto a click 25 optical mount and a 40 mm x 25 mm diameter sleeve, can be fixed onto the mounting plate (02.2126) which is attached to the optical rail using a carrier. The divergence of the magnified beam is adjusted by varying the telescope length.
 

The two high quality front-surface plane mirrors of this module reflect a laser beam within two slightly different angles which causes interference of the beams in their intersection area. The angle between the two mirrors is adjusted by fine pitch screws of the adjustment holder which one of the mirrors is mounted onto.

Dim: 20 mm x 20 mm.
 

In this unit, a semi-transparent mirror plate and a lens with a large radius of curvature are mounted towards each other. A beam shining through this element shows characteristic Newton interference rings. The curvature of the lens can be determined by this interference effect.
The high quality semi-transparent mirror and the Plano convex lens with f = 2600 mm have a diameter of 22,4 mm. Both are fixed onto a 25 mm special anodized aluminum ring mount and are mounted onto a mirror adjustment holder (02.5600) fixed on a carrier 20 mm.
The metal parts are made out of special anodized aluminum.
